Year of most recent IBA criteria assessment: 2010
Populations of IBA trigger species| Species | Current IUCN Red List Category | Season | Year(s) of estimate | Population estimate | IBA Criteria Triggered |
|---|---|---|---|---|---|
| Common Little Bittern Ixobrychus minutus | LC | breeding | 2007-2009 | 12-18 breeding pairs | C6 |
| Black-crowned Night-heron Nycticorax nycticorax | LC | breeding | 2008 | 113-120 breeding pairs | C6 |
Note: This table presents the IBA criteria triggered and the species that triggered then at the time of assessment, the current IUCN Red List category may vary from that which was in place at that time.
